Re: Amplifier for Dynaudio BM15 passive monitors? Thanks!

Hi there,

Could anyone please tell me if I could power my passive BM15s
with a Technics integrated amplifier, which specs are:
4 ohm, 1 khz continuous power output both channels driven 2x100W,
63-12,5 kHz continuous power output both channels driven 2x85W?
If so, is there going to be any difference to my QSC USA 900 power
amplifier
(2x450W at 4 ohm) at all? I've read that amplifier has to be powerful
enough
to fully drive speakers (especially low frequencies),
others say that there is no diference in the amps at all, and that
they all
sound the same with volumes matched, unless they are overdriven.

Is the Technics amp powerful enough and can it drive these speakers
properly?
Is there going to be any loss in the lower frequency range?

Another question: Is it possible to burn/damage the speakers or the
amp
because the amp is not powerful enough? How loud you'd need to get the
volume in this case?

Thank you so much! I appreciate it!

Ray,
Dynaudio's design philosophy leans toward quality over efficiency.
Most of their speakers are a bit lower in efficiency than other
brands, but handle way more power. That said, the Technics will work
fine unless you want to get really loud with lots of deep bass. Beware
the little know fact that under powering a speaker will blow it out
faster than over powering it, due to clipping distortion. The Technics
being a hifi piece probably doesn't say when it is clipping. The
Bryston 2B or 4B is a much better alternative. Look on line for used,
sometimes they are available for $5 or 600. If this scares you stay
with the Technics and keep an eye out for a fast, powerful respectable
amplifier. I think the BM15s are rated at 150 watts but has been a
long time since I needed to know that spec.
Party on.
